Using the generic symbol R · as the initial radical, the first two propagation steps in the polymerization of crotonic acid are to be drawn by paying close attention to regiochemistry. The same is to be done for acrylic acid. Crotonic acid polymerizes much more slowly than acrylic acid. The reason for it is to be explained. Concept introduction: The initiation step is needed to create free radicals. After initiation, propagation occurs via radical addition. A radical, such as benzoyloxyl radical, produced directly from the initiator, adds to other molecule of monomer increasing the length of the carbon chain. The less substituted carbon is called the tail and the more substituted carbon is called the head. The head-to-tail addition of vinyl monomers is usually favored in free radical polymerization. Increasing steric hindrance during head-to-tail polymerization, decreases rate of polymerization.

Answer 1

Question

Definition Definition Chemical process in which one or more monomers combine to produce a very large chain-like molecule called a polymer. The functional groups present on the monomers and their steric effects are responsible for polymerization through a sequence of reactions that vary in complexity. There exists a stable covalent chemical bond between monomers that sets apart polymerization from other processes.
